OSCILLATING FAN.

To all whom t may concern:

Be it known that I, EDWIN PHELPS, a citizen of the United States of America, and a resident of Wilmette, county of Cook, and

, State of Illinois, have invented certain new and useful Improvements in Oscillating Fans, of which the following is a specification.

The main object of this invention is to provide an oscillating fan similar in type to that shown in the/copending application of Willard M. McEwen, Serial No. 40,397, iiled July 17, 1915, and having improved operating mechanism.

An illustrative embodiment of this invention is showu in the accompanying drawings,

- in which: l

Figure 1 is a sectional elevation taken on the .line A-A cf Fig. 2. Fig. 2 is a front elevation partly sectional as viewed from the plane of the line B--B of Fig..1. Fig. 3 is a transverse'sectional detail taken on the line- C-C of Fig. Fig. 4 is a similar view taken on the line D-D of Fig. 2. In the construction shown in the draw ings, a rotary member or shaft 1 is mounted on va base or support 2 and carries blower mechanismy 3 which is pivotally connected thereto by stud shafts 4. The blower mechanism comprises a motor 5 journaled in a housing 6 and connected to rotate the fan 7 carried on the end of the motor shaft 8. The housing 6 is provided with a bifurcated stem 9 which embraces a head or frame 10 on the member or shaft 1, and is pivotally connected to shaft l by means of the horizontal stud shafts 4.

The mechanism for tilting the blower mechanism comprises a cam 11 keyed to a shaft 12, journaled on the stem 9, and located in a slot or recess 13 formed in the head 10. The head 10 is integral with the shaft 1 and the slot 13 is elongated in a direction transverse and at right angles tothe axis of the stud shafts 4 soas to allow for the reciprocation of the cam. The cam 11 is preferably a circular. eccentric embraced by a rin'g 14 i mounted on ball bearings 16; The outside diameter of the ring 14 is substantially equal tothe width of the slot 13 and together with the ball bearings 16 provide an antifriction Specification of `Letters Patent.

19. which is journaled in the casing 6 and connected by worm 20 and gear 2l to'the motor shaft 8. i

The shaft 1 issupported on the base 2 by means of antifriction bearings 22 and 23, the

`bearing 22 being in the form of a plurality 1 vertical plane. The gyratory forces cause a reversal of the direction of the horizontal swinging movement whenever the vertical tilting movement is reversed and the rapidity and angular extent of the horizontal movement depends" upon the rapidity of the vertical movement. v

Although but one specific embodiment of this invention has been herein shown and described, it will be understood that numerous details of the construction shown may be altered or Aomitted without departing from the Patenten Nov. 2s, 191e.
